From my perspective, and I'm certain that many will disagree, is that both Hamilton and Caray were horrible broadcasters. They talked too much. They weren't particularly bright. They thought far too highly of themselves. The cult-like reverence of Harry Caray in Chicago and the statue in front of Wrigley Field sometimes reminds me of the Israelites worshipping the Golden Calf while Moses was on Mount Sinai.
Then again I recall being told as early as 1972 by my mother that Harry Caray was a bad person.
